在使用jdk 1.5而不是1.6时运行时，获取getNamespaceContext（）的NoSuchMethodError

Question

我正在运行一个用Java编写的程序，该程序已部署在Oracle应用服务器上，并运行1.5 JVM。以下是堆栈跟踪：

Exception in thread "main" java.lang.NoSuchMethodError: com.sun.org.apache.xerces.internal.impl.XMLDocumentScannerImpl.getNamespaceContext()Lcom/sun/org/apache/xerces/internal/xni/NamespaceContext;

Process exited.

如果我使用jdk 1.6运行完全相同的程序，则该程序可以完美运行。 这是图书馆参考的特定问题吗？ 有人以前见过这种异常吗？

干杯。

我敢打赌，您的应用程序或Oracle AppServer附带的Xerces实现与JDK附带的实现之间存在冲突。

它可以与JDK6中的版本一起使用，但与JDK 5中的版本不兼容。
